Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial application field) The present invention provides an opening/closing part that opens outward so that the inner surface faces upward on the front and rear sides of the arcuate kneading sole. This invention relates to a tea leaf roughening machine that can safely and easily remove tea astringency adhering to tea leaves.

(Prior art) As shown in FIG. 7, a conventional tea leaf crushing machine is provided with an automatic opening/closing door 26 for taking out tea leaves at the bottom of an arc-shaped crushing base a, and an automatic opening/closing door 26 at the front of a leaf crushing part b. It is equipped with an opening/closing part 27 for cleaning.

(Problems to be Solved by the Invention) In the conventional tea leaf roughening machine described above, since the opening/closing part 27 for cleaning is located in front of the leaf crushing part b, when removing the tea bitterness attached to the rolling bottom a, Since it is impossible to reach the depths of the tea leaves, a person has to enter the tea leaf storage barrel 28 and work in a cramped space between the kneading hands 29 and the leaf holder 30. For this reason, the work is hard and slow, and even on large machines, more than one worker cannot fit inside the tea leaf storage barrel 28, so it takes a long time to remove the bitterness from the tea. Since it is not obvious from the outside that the machine is working inside, there is a problem that other workers may operate the machine without noticing, causing a serious accident that could result in the worker's death.

The present invention was made in order to solve the above-mentioned conventional problems, and by providing an opening/closing part that opens outward so that the inner surface faces upward on the front and rear sides of the arcuate kneading bottom in the tea leaf storage barrel. It is an object of the present invention to provide a tea leaf coarsening machine capable of easily removing tea astringency adhering to the crushing bottom from the outside of a storage barrel.

B. Structure of the invention (means for solving problems) The tea leaf roughening machine according to the present invention whose grinding bottom can be opened is:
A main shaft extends through the center of the tea leaf storage barrel, and the main shaft is equipped with a kneading hand for kneading the tea leaves on the arc-shaped kneading bottom of the storage barrel, and a leaf comb for dispersing the tea leaves at a leaf beating part. In the installed known tea leaf roughening machine,
With this structure, opening and closing parts are provided on the front and rear sides of the fixed part provided with the tea leaf removal door with the arcuate kneading bottom, the lower side of which is screwed onto the fixed part and which opens outward so that the inner surface faces upward. It is about solving problems.

(Function) The tea leaf crusher configured as described above, which can open and close the crushing base, can be opened and closed when coarsely crushing tea leaves by closing and fixing the opening/closing parts provided on the front and rear sides of the crushing base. Since the part is held in an immovable state, kneading by kneading hands can be reliably performed on the inner surface of the sole in the same way as a normal kneading sole.

However, when cleaning the storage cylinder after roughing, the front and rear openings are screwed to the fixed part at the bottom, so they open outward and the inner surface with the duct attached faces upward. At the same time, the front and rear sides of the kneading sole are wide open to allow easy access to the fixed part, making it easy to remove tea stains attached to the kneading sole from outside without entering the storage barrel. The work can be done quickly even with a small number of people, and if there is manpower, the cleaning time can be greatly shortened by having two or three workers lined up in front and behind each other.Furthermore, it is possible to work from outside the machine. If the machine is clean, other workers will be able to clearly see that the machine is being cleaned, and they will not accidentally operate the machine and cause an accident.

(Example) Next, an example of the implementation of the tea leaf coarsening machine according to the present invention, which can open the crushing bottom, will be described based on the drawings.

In each of the drawings, 1 is a tea leaf storage barrel, and its lower part has an arcuate shape as shown in Figures 2 and 3 so that effective rolling can be done by rotating the rolling hands (described later) A well-known duct 2 is installed inside as the rolling sole a, and the upper part is a rectangular tea leaf beating part b so that the tea leaves can be effectively diffused by the leaf scooping described later, and the rear side of the leaf beating part b is As shown in Fig. 1, a hot air blowing duct 3 is provided over the entire width of the storage cylinder 1, and its blowing port 3' is placed on the rear side of the massaging bottom a as shown in Figs. 2 and 3. It is open at the top.

Reference numeral 4 denotes a main shaft that extends through the center of the tea leaf storage body 1 described above, and a kneading hand 5 and a leaf paddle 6 are attached to the main shaft in the relative positions shown in FIGS. is transmitted to the main shaft 4 and rotated at a predetermined speed in the direction shown by the arrow in Fig. 3.The rotation speed can be adjusted automatically or manually according to changes in the properties of the tea leaves or the progress of processing. The rough kneading process is varied to ensure that a good roughening result is always obtained.

Reference numeral 7 denotes a fixed part for the rolling bottom a of the tea leaf storage barrel 1, and this fixed part a is provided with a tea leaf take-out door 8, which is used to finish the coarse rolling of the tea leaves put into the tea leaf storage barrel 1. When the tea leaves are crushed, the tea leaves are opened by an automatic opening/closing means 9 (the drawings and explanations are omitted as they are well known), and the tea leaves are conveyed to a conveyor disposed below using the rotation of the kneading hands 5 and the leaf comb 6. 10 and conveyed to the next process.

11 and 12 are opening/closing parts provided on the front and rear sides of the above-mentioned kneading sole a, whose lower sides are connected to the fixed part 8 by hinges 13 and 14, and whose upper free ends are L.
The free end of the rear opening/closing part 12 is reinforced by attaching shaped steel etc., and the free end of the opening/closing part 12 on the rear side is tightened and fixed to the rear lower edge of the leaf part b with a bolt 15. When the bolt 15 is removed, the opening/closing part 11 is attached to the inner surface. The opening/closing part 12 is opened outward so that the opening/closing part 12 faces upward, and when the hanging rope of a known spring balancer is connected to the opening/closing part 12 at the time of opening and closing, the heavy opening/closing part 12 can be easily handled by one worker. Therefore, it can be opened and closed safely.

In addition, the front opening/closing part 11 has adjustable length bolts 16 attached to both ends of the free end (sometimes provided in the middle) using a universal joint 17, and this adjustable length bolt 16 is attached to the front lower edge of the leaf part b. Insert the positioning nut 19 into the hole in the receiving plate 18 until it touches the hole, then screw the locking nut 20 from the bolt tip.
0, the opening/closing part 11 is fixed, and when the locking nut 20 is removed and the adjustable length bolt 16 is pulled out from the hole in the receiving plate 18, the opening/closing part 11 opens outward with the inner surface facing upward. When fixing with the adjustable length bolt 16 in this way,
When the positioning nut 19 is moved outward as shown in FIG. 4, the free end of the opening/closing part 11 moves inward and approaches the leaf holder 6, changing the direction of picking up the tea leaves and creating a leaf-pulling state. Easy adjustment from outside while the machine is running.
Because it can be done quickly, it is extremely convenient in terms of operation compared to the conventional method, in which the machine is stopped, a large number of leaf paddles 6 are moved, and the spacing from the crushing bottom a is changed to adjust the leaf beating condition. In addition, since the leaf beating condition can be changed quickly, there is no deterioration in the quality of the product.

Note that the receiving plate 18 of the adjustable length bolt 16 described above is
The angle does not change when the closing and fixing position of the front opening/closing part 11 is in the standard position as shown in FIGS. 2 and 3, and in the position to reduce leaf blowing as shown in FIG. 4. Since this is inconvenient for tightening, it is attached to the mounting plate 24 using the pivot bolt 21 and the fixing bolt 23 that engages with the arcuate long hole 22.
When the fixing bolt 23 is loosened, the angle of the receiving plate 18 can be changed in accordance with the change in the closed and fixed position of the opening/closing part 11.

Reference numeral 25 denotes a leaf-beating stop provided on the inside of the front part of the above-mentioned leaf-beating part b, and when the tea leaves picked up towards this by the above-mentioned leaf paddle 6 hit, they fall downward, reducing the leaf-beating effect of the tea leaves. It has the effect of causing

C. Effect of the invention The tea leaf roughening machine of the present invention, which can open the rolling sole, can rub tea leaves as well as a normal rolling sole if the opening and closing parts provided on the front and rear sides of the rolling sole are closed and fixed. However, when the opening/closing part is opened, the opening/closing part opens outward with its inner surface facing upward, and the front and back of the kneading sole are opened wide, allowing access to the depths of the fixed part. The task of removing tea stains from the bottom of the kneading machine has become extremely easy and can be completed even by a small number of people.
In addition, if there is enough manpower, it is possible to have several people working on the task, which can significantly shorten the cleaning time.Furthermore, if the work is done from outside the machine, it is easier for other workers to see the work while it is being cleaned. This will completely prevent you from accidentally operating the machine and causing an accident.

In addition, if this coarse rolling machine is configured to close the front opening and closing part and change the fixing position from inside to outside, the distance between the rolling bottom and the leaf can be quickly changed by operation from outside the machine, and the leaf rolling process will be completed. This has a unique effect in that it is also possible to make adjustments.
